That’s not rayfish handling that but the cloudflare DDNS you’re using that handles that. So yes, self hosted WG server handles that just as fast.
If you’re talking client IP, it will reconnect as fast as whatever internet connection you’re switching between allows it. For me it’s something like 3-5 seconds from disconnect to reconnect.
Dude, a self hosted WG server creates a tunnel network without relying on central servers. Rayfish is probably just an AI-coded WG server and client combo. It’s “solving” a problem with AI that was already solved without AI.
